This invention relates to windows of the type that are movable about ahorizontal axis, midway between the top and bottom thereof and moreparticularly has reference to a control device for adjustably moving thewindow between a closed position and a ventilating position andpermitting complete opening of the window.

An object of the invention is to provide a control device on ahorizontally pivoted window sash and means on the window framecooperating with the control device to lock the window sash in closedposition and to secure the window sash in various partly open positions.

Another object of this invention is to provide a control device on ahorizontally pivoted window sash and means on the window framecooperating with the control device to lock the window sash in closedposition and to secure the window sash in various partly open and fullyopen positions.

As shown in the drawings, the present invention is embodied in a windowcomprising a fixed frame I and a sash 2 pivotally mounted in the frameby means of two hinge members I and II, to swing about a horizontal axisintermediate the top and bottom of the sash.

A hinge member II is attached to ach side of the sash 2. Projecting fromeach hinge member II is a pivot element 3 and a pivot pin 5.

A hinge member I is attached to each side of the window frame I tocooperate with the corresponding hinge member II. As clearly shown inFigures 3-5, the hinge member I is provided with an abutment 4 forcooperation with the pivot member 3 of the sash and an arcuate slot 6for guiding pivot pin 5 of the sash. Slot 6 is open at the top andclosed at the bottom.

With the hinge structure shown in Figures 3-5 and described above, thepivot members 3 support the sash in the closed position and bear on theabutments 4. As the sash is opened, the sash is pivoted in acounter-clockwise position about an axis defined by the engagementbetween the lower portions of the pivot members 3 and the abutments 4 ofthe hinge members and the pivot pins 5 move downwardly in the arcuateslots 6 until pins 5 engage the bottom of the slot.

Further movement of the sash 2 in a counterclockwise direction causesthe sash to be pivoted about a horizontal axis defined by the pins 5 inthe bottoms of the slots 6. Under such circumstances, the pivot member 3leaves the abutment 4 as shown in Figure 6 of the drawings.

According to the present invention, the window sash 2 is provided with alongitudinally slidable member 8 on each side thereof. Thelongitudinally sliding member 8 is associated with the sash as isclearly shown in Figure 8 of the drawing. Movement of the longitudinallysliding members 8 is effected by means of a cable surrounding theopening in the sash and actuated by means of a control lever Ill locatedat the bottom of the sash. As the control lever is moved in onedirection, the member 5 on one side of the sash will be moved upwardlyand the corresponding member 8 on the other side of the sash will bemoved downwardly.

Projecting laterally from each vertically slidable member 8 is a pin 1.In accordance with the present invention, a member Ia is locatedadjacent each hinge member I on each side of the window frame. Asclearly illustrated in Figures 3-5, each of the members Ia is providedwith a curved slot for cooperation with the pin I carried by thevertically sliding member 8.

Figures 3-6 illustrate one suitable form of slot 9 in member Ia forcooperation with pin 1. This slot is open at one side of the fitting Iafor the introduction and removal of pin 1 as the sash is swung about itspivot axis. From the open end, slot 9 is inclined upwardly as indicatedat 9b to a predetermined point and then is oppositely inclineddownwardly as indicated at 9a to the closed bottom. The closed bottom ofslot 9 is disposed opposite the open end of the slot.

When the sash is in the closed position, pin I is located at thebottomof slot 9 as shown in Fig. 3. To open the sash, lever it! is shifted tocause the slide member 8 to move vertically along the side of the sashand to shift pin '5 upwardly. The upward movement of pin 1 through theportion of slot 911 causes the window to shift about its pivot axis asshown in Fig. 4.

The downward movement of pin '1 through the portion 91) of the slot isproduced by shifting lever in the direction opposite that of its firstmovement and the application of a slight force on the sash urging it toan open position. This downward movement of pin 7 will cause the sash tobe further moved in a counter-clockwise direction about its pivot untilthe pin reaches the lower open end of slot 9.

Lever it, in addition to operating the sliding members 8 carrying thepins I, also serves to actuate the locking pin carried by the sash forcooperating with slots in looking members carried at the upper and lowerportions of the sash. The inclination of the portion 9a of the slot inthe members Ia corresponds to the inclination of the slot in the lockingmembers carried at the upper and lower portions of the window so thatwhen lever to is actuated to move the locking pins to an unlockedposition, the movement of pin 7 in the portion 9a will shift the sash 2through the proper angle about its axis to correspond with the movementimparted thereto by movement of the locking pins in the locking slots.

When the pin d is moved into the portion 9b of the slot in the membersIa, the locking pins also actuated by the lever iii will have left theirslots. By shifting the lever. to a selected position, the pin 7 may bemoved to a corresponding position within the slot 92) so that the windowsash 2 will be inclined at the desired angle to maintain the sash in apredetermined partly opened position.

While the member Ia may be separate from the member I, it is desirablein some instances to have it formed as a part of the member I.

The control device is such that when the lever M has been moved in onedirection and the window is unlocked, the lever has to be moved back inorder to push the pins 1 into the outer parts 9b of the slots 9. Thismovement is facilitated by controlling the lever it with one hand andwith the other pushing the sash 2 in the direction of movement. With thecontrol lever it! it is very easy to obtain the desired size of theventilation openings between the frame and the sash at the upper andlower sides. By moving the control lever in the opposite direction topush the pins I into the outer parts so of the slots 9, the controllever does not need to be turned essentially more than is required forthe control of the locking pins. The control lever It! may be providedwith means for securely holding it in certain desired positionscorresponding to certain desired ventilating or partly open positions ofthe sash.

As before stated, when lever 19 is shifted, the pin 1 on one side of thesash will be moved in one direction and the pin 1 on the opposite sideof the sash will be moved in the opposite direction. Due to the oppositemovement of the pins 7 on the opposite sides of the sash, the slot 9 ofthe fitting Ia on one side of the window frame will appear as shown inFig. 3 and that on the opposite side of the frame will appear as in Fig.'7.

Instead of forming the slot 9 as shown in Figs. 34, it may beconstructed as shown at IS in Figs. 10 and 11. According to thisembodiment, the pins '1 are moved into the ventilating range lflb of theslots [9 by shifting the control lever E5 in the same direction when thesash is unlocked and when it is opened for ventilating purposes. It isclear that the difference between this embodiment and that of Figs. 1-9is that the inner part iSa of the slot according to Figs. 10 and 11forms an approximately tangential extension of the arcuate outer partI91) while the parts 9a and 912 according to Figs. 1-9 are connectedwith an arc and form approximately tangential extensions thereof.

The slots 49 may have one or more recesses i I in the margin of theouter parts iQb into which the pins 1 may be brought to securely holdthe sash in a certain open position or in any or" a number of definiteventilating positions.

As far as the invention has been described in connection with Figs.1-11, it serves for control and holding of the sash in ventilatingpositions in which the sash is pivoted only a small angle with the lowerside outwardly from the closed position with small ventilation openingsat the top and bottom of the. window. The specially formed slot 9 forcooperation with the ventilating pin 1 may specially be used where it isdesired to finely control the size of these'openings. The control deviceaccording to the invention, however, may also be utilized where it isdesired to control the sash in open positions between and from theclosed position. For that purpose the fitting I or another fitting maybe provided with one or more so arranged recesses I2 that the movablepin 1 in the sash actuated by the control lever maybe inserted into anyone of these recesses when the sash has been pivoted to a position inwhich the recess lies in the line ofmotion of the pin 1 (Figs. 12, 13,15 and 16). When the pin 1 engages in one of the recesses i2, the sash 2is securely held in the corresponding position. In windows with a sashpivotally mounted on a median axis it is often desired easily to be ableto set the sash not only in ventilating positions in which the sash ispivoted, only a small angle from the closed position, but also inpositions in which the sash is pivoted to positions from 90 up to 180from the closed position. As shown in Fig. 16, the slot 9 may bereplaced by an arcuate element provided with recesses I3, arranged inthe fitting Ia, preferably integral .with the fitting I, which aresimilar to the recesses l2, only with the difference that they arelocated so that the pins 1 may be inserted into them when 5 the sash isin positions between and about 90 from the closed position.

The slot in the member Ia may have various forms. As shown in Fig. 15,slot 29 may have three inclined legs instead of two as shown in Figs.37, 12 and 13, so that the pins 1 must be moved from closed positiontoward open position, then to closed position and again towards openposition to shift the sash from closed position through the ventilatingpositions.

Figs. 17-19 are detailed views of hinges and control devices of amodified embodiment of the invention, which is especially suitable foruse in windows of the type where the sashes when unlocked owing to theirgravity and their sus pension tend to take a certain balanced and stableopen position. The details of the hinges correspond to those alreadydescribed and have similar reference characters. Movable pins 2|,however, in this example have been arranged in one side of the frame inguides 22 which can be made in one piece with the adjacent fitting partI of the hinge. Pins 2| are carried by longitudinally slidable members(not shown) similar to members 9 of Figure 8. The fitting II mounted onthe sash has an extension with a slot 23. When the pin 2| which in Fig.17 is shown in the upper end of the guide 22, is moved downwardly, itenters the slot 23 and the sash is pivoted as indicated in Fig. 18. Ifthe pin 2| is moved further against the lower end of the slot 22, thesash is pivoted to the balanced position in Fig. 19. The pin 2| is thenout of the slot 23 in the fitting II which has such a shape that thesash is free and may be freely pivoted in one or the other direction onone of the pins 3 or 5 and secondly by the control device may be pivotedto a smaller opening and closed. The fitting with the slot 23 is soarranged on the sash that the pin 2| when it is moved back automaticallyenters the slot 23. The advantages of this construction reside in thecontrol and secondly in that the pin 2| is disengaged when the sashreaches the balanced position.

A common feature of all the described embodiments of the invention isthat the pins 1 or 2| for controlling of the different openings of thewindow in contradistinction to closing and locking in the closedposition are movable at right angles to or near right angles to thepivotal axis of the sash, that is to or from the axis. Among the manyobvious advantages in this arrangement is that the device is verysimple, reliable and easy to control and it can easily be varied intomany different embodiments according to the requirements.
